I actually like it. I didn't see this error cuz I was only building
musb for arm architecture.

But why only davinci and omap?
What about: mach-aaec2000, mach-at91, mach-ep93xx, mach-integrator,
mach-lh7a40x, mach-ns9xxx, mach-pnx4008, mach-pxa, mach-realview,
mach-sa1100, mach-versatile, mach-s3c24x.
